Held along Alaska’s famous Iditarod trail during the famously harsh Alaskan winter, runners cross the tundra either on foot or by bike and have to be self supported. To qualify for the full distance race, you have to have proved yourself in the shorter 350 mile race the year before. Needless to say, running in an Alaskan winter is a bit chilly never mind dragging a sled behind full of your supplies to keep you going in vast wilderness.
